I sent the same message in september 2000, but nobody answer me. I try again.

[Delphi 3 C/S]
3-tiers project
In the server side:
I use a query in a TOracleDataSet plugged to a TOracleProvider. In the OnGetData event of the provider, I scroll the records of the dataset and change the value of a field. This field can't be updated by the client.

In the client side:
When I try to post an update, I have the message 'Operation not applicable'.

If I don't put any code in the OnGetData, the update works well.
